IPC: H02M3/155
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a power conversion device which is free from unbalanced input voltage, capable of maintaining high power conversion efficiency using relatively simple circuitry. SOLUTION: A power conversion device contains two parallel-connected half bridge inverters 3A, 3B, and turns on/off switching elements, using the voltage of a series capacitor as an input voltage. A direct-current power supply 1, such as a solar cell, is connected with both the ends of a capacitor 6. Two switch arms are connected vertically with each other in series to form a series switching circuit 38. The circuit 38 is parallel-connected with the series circuit of the capacitor 6 and a capacitor 15, and a reactor 10 is connected between the point of interconnection between the upper and lower arms of the circuit 38, and the point of interconnection between the capacitors 6, 15 to form a direct-current voltage-dividing circuit 2.  Switching elements 4, 13 in the series switching circuit 38 are on/off-controlled, so that the voltage of the capacitor 15 not connected with the direct-current power supply 1 be equal to the voltage of the capacitor 6.

Title: Zinc alkali battery
Inventor: MIURA AKIRA
IPC: H01M4/42
Filed: 1984-12-12
Abstract: PURPOSE:To obtain a low pollution alkali battery by employing zinc alloy containing Ni and Ag within proper content for the negative pole thereby reducing the hardening rate of negative pole alloy. CONSTITUTION:Zinc alloy containing 0.01-0.5wt% of nickel and 0.01-0.5wt% of silver is employed for the negative pole of zinc alkali battery. When adding Ni and Ag to negative pole zinc, remarkable corrosion-proof effect is achieved when compared with the case where said element is added independently. It is presumed that the affinity with mercury on the surface of zinc alloy is improved through addition of Ag while Ni will contribute to suppress dispersion of mercury into the particle to improve the corrosion resistance considerably through formation of zinc alloy surface having high hydrogen overvoltage. Remarkable complex effect is recognized only when the content of Ne and Ag in zinc alloy composition is within said range. Consequently, a zinc negative pole having low hardening rate while provided with discharge performance and corrosion resistance can be obtained.

Abstract: PURPOSE:To prevent tungsten from biting into the lower side of an interlayer insulating film by a method wherein, before a contact hole is filled with tungsten, ions of silicon are implanted and a lamp annealing operation is executed. CONSTITUTION:Before an aluminum wiring part is formed, ions of silicon are implanted into a sliced whole face of a substrate by an ion implantation method; after that, a lamp annealing operation is executed. By this operation, a concentration of silicon inside a contact region under a contact hole filled with tungsten is increased. That is to say, the silicon exists apparently excessively in a direction perpendicular to a wafer 5 from the lower part of the contact hole. Accordingly, the silicon as a reducing agent is supplied from the direction perpendicular to the wafer 5. i.e., from a direction of a concentration distribution. Thereby, the tungsten is grown in the direction perpendicular to the wafer; a reaction in a direction below an insulating film is not caused; the tungsten does not bite.
